I second Phil that the CS is not scooped, but balanced on the mids. It doesn't really peak there, although it has a certain hairy raunch to it which I love. The bottom is tight and full.
Out of the two, I guess the PK is tighter. It has it's voice more in the mids, a lot of high mids. Out of the two, PK is more modern, CS has a bit more vintage voice in it.
